Title: Heat exchanger
Inventor: SAITO YUTAKA
IPC: F28F13/02
Filed: 1988-09-30
Abstract: PURPOSE:To improve both of the heat transfer characteristics of evaporation and condensation at the same time by forming a porous layer having pores in its inner wall, providing a heat transfer pipe which has an increasingly smaller rate of the porous layer formation from one end of it toward the other end, and using a grooved or smooth surface for the inner wall at the other end. CONSTITUTION:The inner wall of hair pin tubes 6a, 6b, 6c has on it a porous layer such as reentrant cavities produced by the sintering or plating of metal. The hair pin tubes 6a at the inlet of the evaporator for a heat exchanger 8 has a porous layer having a greater porosity, and, as it advances nearer to the evaporator inlet side from the hair pin tube 6b to 6c, the porosity of the porous layers becomes less porous. A similar effect can be obtained by making the hair pin tube 9a of the heat transfer pipe 2 on the evaporator inlet side of a heat exchanger 10 a porous layered tube, and using a grooved or smooth surfaced tube for the hair pin tube 9b on the evaporator outlet side.

Title: Light emitting output variable element
Inventor: SEKII HIROSHI
IPC: H01L27/15
Filed: 1984-11-20
Abstract: PURPOSE:To variably produce a light emitting output variable in the amplitude of a forward current flowing to a light emitting P-N junction by applying a reverse bias voltage to a gate P-N junction to alter the amplitude, thereby varying the depletion layer of the gate P-N. CONSTITUTION:A forward voltage is applied to an anode 10 positively and to a cathode 8 negatively, a gate power source switch 11 is opened. Thus, since large forward current is flowed to show by an arrow in the state that a gate electrode 9 is not applied by a reverse bias, strong light is obtained. However, when a gate power source switch 11 is closed to apply a reverse bias voltage to the electrode 9, a depletion layer of a P-N junction is extended, and the width of the gap between insulating layers 3 is narrowed. Therefore, the forward current flowed thereto decreases to reduce the emitting light output. If the reverse bias voltage applied to the electrode 9 is increased more, the emitting light output decreases more.

Title: Metallic filter and its production
Inventor: SONOMOTO KAZUHIKO
IPC: B01D39/20
Filed: 1994-10-13
Abstract: PURPOSE:To prepare an inexpensive metallic filter having fine pores and having good filtering property and high mechanical strength by pressing a wire net woven like a rush mattress (tatami mattress for lapeness domestic life) at a specified draft and specifying the pore diameter after pressed. CONSTITUTION:This metallic filter is obtd. by pressing a wire net woven like a rush mattress ('tatami'). The draft for pressing is preferably 2-50%, and more preferably about 20% to about 40%. The pore diameter of the pressed wire net is preferably 5-120mum. Further, it is preferable to subject the wire net to heat treatment after pressed so as to improve the bonding strength of the pressed part since the bonding strength in the crossed part of the longitudinal lines and transverse lines is weak. The heat treatment may be regarded as one kind of sintering, and when a powder phase layer is formed by applying a powder on the metal mesh as a substrate, this sintering process acts as the heat treatment. Thereby, an extremely inexpensive metal filter having good filtering performance and production efficiency is obtd.

Moreover, a second laser oscillator 1110 is present in this system and an AOM 120 modulates a second beam independently. Then, these two beams scan on a curved image surface 165 without the spin element or the wobbling element in order to provide multiple scanning lines which do not intersect each other on the curved image surface 165.

Abstract: PURPOSE:To improve the secondary breakdown withstand of a field effect semiconductor device by forming a diode region of another second conductive type semiconductor region to be accurately distinguished from a portion which achieves the function by a field effect on the surface of the first conductive type semiconductor substrate.

Title: Manufacturing of electrodeposited whetstone
Inventor: OKUNISHI HIROSHI
IPC: B24D11/00
Filed: 1983-12-27
Abstract: PURPOSE:To prolong the lifetime of a master base metal by interposing a low melting point metal as a temporary support material between a metal-plated layer, which holds abrasive grains on its surface, and a master base metal and by dissolving/exuding the metal, at the time of hot-bonding this metal-plated layer to the whetstone base, so as to separate the master base metal from the plated layer and abrasive grains. CONSTITUTION:Abrasive grains 3 are dispersed on the surface of a base metal 1, and the tips of those grains near the surface are temporarily held by a low melting point metal layer 4. A metal-plated layer 5 is provided so that it may cover the base parts of the abrasive grains 3 protruding from the surface of this metal layer 4; thus the whetstone master is made up of the metal layer 4, the abrasive grains 3, and the metal-plated layer 5. This whetstone master is placed on a whetstone base 7 so that the surface of the metal-plated layer 5 may perfectly overlap the surface of the whetstone base 7 to make them into one body. The whetstone master and the whetstone base 7, which have been made into one body, are heated to melt the low melting point metal layer 4. Thus the whetstone master metal base 1 is separated from the whetstone base 7, allowing the reuse of the base metal 1. And the tips of the abrasive grains 3 come out from the surface of the metal-plated layer, resulting in obtaining an electrodeposited whetstone.

Abstract: PURPOSE:To provide a product clear of bubbles with a uniform thickness with an easy manufacture of a mold by placing a powdered resin in fluid into a heated mold to produce a melted resin layer, which is cooled to make a skin material. CONSTITUTION:A powdered resin in fluid is shifted into a mold heated to a produce a melted resin layer, which then, is cooled and solidified to obtain a skin material. For example, a powdered resin 18 such as polyvinylchloride is charged into a retaining tank 1 and a mold 5 heated up to about 300 deg.C is clampled so as to close the opening 2 of the retaining tank 1 with the molding surface 5a downward. When fed into a chamber S2 through an air introduction port 6 of the retaining tank 1, air enters a chamber S1 through a filter 7, where the powdered resin 18 is fluidized as if floated. Thereafter, a motor 15 is driven to turn the retaining tank 1 by about 270 deg.. In this manner, the powdered resin 18 contacting the molding surface 5a of the mold 5 is melted to form a melted resin layer 19. Then, the mold 5 is cooled until the melted resin layer 19 is solidified to obtain a skin material.

In steps 13b...13c, Q2 to Qn are calculated by filtering with the phases each shifted by the sampling period while step 13a is used as a reference. In steps 14, 15, the quantity of intake air calculated at the filter at which DELTAQ is at a minimum is employed as a current optimum value.

Title: Mos transistor and manufacture thereof
Inventor: SHIMIZU MASAHIRO
IPC: H01L29/78
Filed: 1988-09-30
Abstract: PURPOSE:To obtain a large current driving capacity and a good characteristic by a method wherein a medium-concentration impurity diffusion region of a double-diffusion source-drain structure is arranged to be adjacent to a high- concentration impurity diffusion region in such a way that the whole of the region is overlapped completely with a gate electrode. CONSTITUTION:A lower-layer gate electrode 3 is formed on a P-type semiconductor substrate 1 via a gate oxide film 2; an upper-layer gate electrode 7 is formed on the lower-layer gate electrode 3. A thickness of the lower-layer gate electrode 3 is thinner than that of the upper-layer gate electrode 7; regions 4a, 4b of a medium-concentration N<-> impurity active layer are formed to be adjacent to N-type high-concentration impurity active layers 7a, 7b in such a way that the respective whole regions are covered with the gate electrode. Accordingly, a charge storage layer is formed, by means of an electric field, in a substrate region situated directly under the gate electrode 3. Thereby, it is possible to suppress a drop in a driving capacity by a parasitic capacitance of the medium- concentration N<-> impurity diffusion regions 4a, 4b; in addition, it is possible to suppress a deterioration in a characteristic by a hot carrier.
